I was told today that many Windows MUAs that cannot filter against
arbitrary headers such as X-DCC can filter against Subject headers.
Do you think that's true enough to justify adding options to dccproc
and dccm to modify Subject headers?
If so, do enough of these MUAs have fancy enough Subject header filtering
to detect a string like "X-DCC spam" prepended to the original subject,
or would the entire Subject line need to be replaced? (and, of course,
preserved as something like X-DCC-ORIG-Subject)
